EK122
The calculated amounts of torsional reinforcement must be provided in addition to the full bending and shear reinforcement requirements for the ultimate load combination corresponding to the torsional moment considered.
EK119
Concrete is weak in tension. Microcracks begin to generate in the matrix of a structural element at about 10% to 15% of the ultimate load, propagating into macrocracks at 25% […]
EK79
If we assume that the uniformly distributed load is that which causes a full pattern of yield lines to be produced, i.e. a collapse mechanism, we have an ultimate load […]
EK78
The object of the yield line analysis is to determine the relationship between the ultimate load and the ultimate moment of resistance of the band(s) of reinforcement.
